refactor: move sourcing_link and standard_cost from item columns to revision properties

- Add migration 013 to copy sourcing_link/standard_cost values into
  current revision properties JSONB and drop the columns from items table
- Remove SourcingLink/StandardCost from Go Item struct and all DB queries
  (items.go, audit_queries.go, projects.go)
- Remove from API request/response structs and handlers
- Update CSV/ODS/BOM export/import to read these from revision properties
- Update audit handlers to score as regular property fields
- Remove from frontend Item type and hardcoded form fields
- MainTab now reads sourcing_link/standard_cost from item.properties
- CreateItemPane/EditItemPane no longer have dedicated fields for these;
  they will be rendered as schema-driven property fields
